Color Wheels are STILL alive!

[hposter]

While scanning the BBC News site, I discovered this little treasure:

". . . The brainchild of Texas Instruments, Digital Light Processing (DLP) first appeared 20 years ago. The key to DLP in a video projector are optical semiconductors covered in millions of tiny mirrors. . .

There is one drawback to DLP. For a chip to produce colour images, a spinning wheel fitted with coloured filters is placed in front of it. . . "

Seems I heard something about spinning wheels to see color, and it didin't start 20 years ago! Where's Colortel when you need them?
